Fuel Economy

[07WYarisRS]

I got my worst two tanks of fuel this past week with hours of sitting in traffic waiting at us/canada customs every day. Still got 500km to a tank, filled the tank and it cost me $25 US for 8.5 gallons @ $2.93 a gallon Sunoco fuel.
I won't run that crap any more.
I usually get about 600km in the same conditions.
I get better mileage running the fuel from Mobil or Sonic.

555 km with a 45.19L fill up (45L bc I was right near empty, so I needed to put $5 in it to get me to Newmarket to visit a friend where gas was priced 7 cents cheaper than here locally)

I guess about 300 KM of them were highway kms... on the 400 and 404, but whenever I'm on these roads I usually on average traveling like 140km (sometimes higher at 150km/h and sometimes lower around 120km/h)

That must be whats killing my fuel efficiency, the high speeds at which I'm travel is just needlessly burning extra fuel.

Im not massively concerned about the low mpg on my yaris, bc if I was driving any other car it would also only be worse than the estimates when traveling at such speed.

Though, maybe I will think about traveling a more regular 110km/h next time I'm going to Toronto and back, to try to really improve that fuel efficiency.

I had no idea that traveling at such speeds really was killing my mpg so badly. (sad)

Yeah, I found it hurt a bit when I go near 160km/h on 404. To balance it out, what I do is the following:

Try accelerate the car under 2500rpm on lights. It's hard, because most car would pass you, but it saves sh!tload of gas.
Only turn on A/C on highway, and turn it off when in traffic. Sure, it's hot as hell sometimes, but it's already september, this should be easier than May or June.

By doing so, I get an extra nearly 50~70 km on a tank.

just filled up @ $2.65
& got my best tank yet at 41.2mpg
my running average since i purchased is 40.1mpg

im happy.

New tank, filled up Monday, got 7.29 L/100 km.

Thats an improvement, but still not even the city mileage I was looking for atleast. :(

NOT that I am doubting you but it just seems impossible to consistantly get that average unless you are on a long road trip. What city/highway % do you drive. How are you calculating your average? 87 oct?

I think it is appropiate to start a thread for fuel economy here so that members can exchange information on this important topic. My car(see right) has been giving me about 14 kilometers per liter i.e.7.14 liters per 100km. That is about 39.5 miles per imperial gallon or 32.9 miles per US gallon. I believe my numbers are about average among fellow Yaris drivers. I look forward to seeing more postings on this subject.

My average (after 5 tanks) is 35.6 MPG (US GAL)

Picked this site up from gassavers.org, it is for bike routes but tells an interesting story if you put your commute in.

87 oct, yea, regular unleaded.

city/highway *may* be 50/50 or 75/25, in that range.

What I meant was, that if I'm doing say 50 or 25% city driving, you'd think id AT LEAST get the stated city mpg as a bare minimum, or in fact get higher, as I do have a significant portion that is highway.

Ive curtailed my fast speeds, and have tried to coast on the 400 and 404 around 110km/h, 120 TOPS... and not for long, maybe when passing only if I can.

I would ask you to define vehicle dynamics...? And quality? This Yaris's fit and finish are excellent.. but in a utilitarian fashion. It's a perfect example of form follows function.. I wanted a compact exterior with a roomy interior, that had all the amenities (P/S, P-Locks, ABS, Cruise, good sound, and air bags, that got better than 30mpg. Well, thats the Yaris.. It's not a sports car, nor is it supposed to be. It's a road-trip, commmuter car and at that it excels.

When the Yaris is viewed for what it is, it's darn near perfect.

At over 4600 miles I am now getting 38mpg+ on every tank and on many 60 mile commute segments breaking 41mpg with no issue at all. Air on or off. It is also an Automatic. Doing the speed limit seems to be the biggest contributor.

If you ever decide to upgrade your wheels, let me know.

BTW I do give a shit and am having fun tracking and improving with my new scanguage.

Odometer 1100. Mostly highway driving.
Mileage 32.7 US mpg. I hope this gets better. I've been driving about 70mph on the highway, maybe I should slow down even more.

The Canuck 5 door is pretty much the same as the xA, so I should be able to do a few mpg better.

I'm comfortsble doing 70 in my Camry surrounded by airbags. In my Yaris? NO WAY!

I'll bet 65 gets a solid improvement!

Air on?

[nsmitchell]

I've noticed that if I use the bathroom just before leaving to go to or from work, I get better mileage because I'm not speeding as much. Think about it.

[stuffy]

you also are not as heavy :)
